Specifications

•
Kernel crash might happen when a router running a Junos OS install with the fix to PR
937774 is rebooted. This problem will not be observed during the upgrade to this install.
It occurs late enough in the shutdown procedure that it shouldn't interfere with normal
operation. PR956691
•
When micro Bidirectional Forwarding Detection (mBFD) is configured on aggregated
Ethernet (AE) interface, if a member link of the AE interface is removed, if a member
link is marked admin down or disabled at CLI, the BFD session would correspondingly
be down. However, the corresponding member link in the peer end continues to forward
traffic. PR963314
•
In a very uncommon situation, we see that LCCs chassisd state is inconsistent with
SFC chassisd state. This is very misleading in troubleshooting stage. PR963342
Layer 2 Features
•
Service accounting interim updates not being sent. PR940179
•
In the unified in-service software upgrade (ISSU) for Dynamic Host Configuration
Protocol (DHCP) scenario, when ISSU initiates, if there are some subscribers stuck in
login state and keep sending discover/request packets, this leads to ISSU ready check
failing and ISSU aborting as a result. PR949337
•
IP address change of a DHCP relay interface does not get reflected in gateway IP
address (giaddr) when maintain-subscribers knob is enabled, which needs to restart
DHCP daemon to make it work again. PR951909
•
When link level adjacency across IRB interface goes down, targeted LDP session might
also go down even if there is a alternate route. PR959396
MPLS
•
When static LSPs are configured on a node, RPD could assert upon committing a
MPLS-related configuration change. Example: router> show system rollback compare
9 8 [edit protocols mpls] interface ae11.0 { ... } + interface as3.0 { + admin-group red;
+} [edit protocols isis interface as3.0 level 2] ! inactive: metric 2610; The following
error is seen in /var/log/messages in-relation to a static lsp, immediately following the
above-mentioned configuration change: rpd[1583]: UI_CONFIGURATION_ERROR:
Process: rpd, path: [edit groups STATELESS_ARIADNE protocols mpls
static-label-switched-path static-lsp], statement: transit 1033465, static-lsp:
incoming-label 1033465 has already been configured by this or other static applications.
PR930058
•
MX Series routers with FPCs could crash during next-hop resolution triggered by indirect
next-hop change. PR944393
•
In certain circumstance, the Junos OS rpd route flash job and LDP connection job are
always running, starving other work such as stale route deletion. These jobs are running
as LDP is continuously sending label map and label withdraw messages for some of
the prefixes under ldp egress policy. This is due to LDP processing a BGP route from
inet.3 for which it has a ingress tunnel (the same prefix is also learned via IGP) creating
a circular dependency as BGP routes can themselves be resolved over a LDP route.
